5 Minute Dungeon Tray Insert - Vertical Storage Solution

I travel with 5-Minute Dungeon a bunch and got fed up with the cards falling out.
I also store it vertically.
The pre-existing insert is actually pretty nifty but not when stored vertically. This print aims to fix that with a low filament (~30g) solution.
Print 1x the center piece, which fits very snugly into the middle of the tray and keeps the bosses + character sheets in place.
Print 2x the side pieces and hook them onto the tray. Fit the dovetails together and voila, it'll hold everything in place.
I print the side pieces on their sides, with supports , to ensure they are strong and the hook part won't snap off (see picture for orientation).
The fits are TIGHT, so maybe measure your box before testing it out.
